There is no leering, no touching and definitely no sexual activity. It is a family-oriented place where the majority of members are mums, dads and children.

In fact, committee member Bob said: "If someone walked in here with clothes on, they might get people staring at them. But if they then took their clothes off, everyone would lose interest and look away."

There are around 50 members of the Oakwood Sun Club, including Terry and his wife who are the last two founding members of the group.

Members enjoy miniten - a version of tennis - at the Oakwood Sun Club naturist site.

Terry decided he wanted to give naturism a go in the early 1960s, and after persuading his wife, they went to try out a club in Southend.

Eventually they branched out and helped start Oakwood in 1962.

"When I first went to a naturist club, I felt like I was walking into a different world," Terry said.

"I walked through the gate and I shut off the outside world. It's hard to put into words, but you feel relaxed and free."
